The id3 BioSeal solution consists of inserting a visible digital seal on a document in the form of a two-dimensional barcode carrying the essential information of the document as well as the biometric face and/or finger data of its owner. According to a company statement, the high-density structure of the BioSeal barcode can store up to 2,000 bytes of information in a small, unmodifiable code.

A digital signature guarantees the identification of the issuing body and the integrity of the document and built-in biometric data allows fully offline biometric authentication to guarantee the identity of the document owner. There is no need to connect to a remote server or a centralized database.

id3 notes that BioSeal is a green solution, able to be stored on a mobile phone for later identification, or printed on recycled paper or biodegradable material if needed. Id3 Bioseal is suited for applications such as access badges, official documents, ID documents, driver’s licenses, certificates and diploma.
